Ask questions about the PhD application process! in Biology Posted January 20, 2019 Hey everybody, Recently, my PI and I have not been getting along with each other well. He has been saying negatives about me behind my back to my labmates, shifted the majority of my project duties to the other RA, and all in all has been very indirect and passive aggressive with me. Needless to say, he will not make a good candidate for a LOR writer unless we reconcile somehow. I'm wondering what I should do-- wouldn't not having him as a writer send off red flags to admission committees? I don't care about getting into a prestigious program, but I'm scared that either having 2 non-research references (1 of my decided letter writers is just a professor I took classes with already, and I won't have any other research professors to write a letter in my current PI's stead) or an unflattering one from him will destroy my chances of getting into any program in general. Please advise.
